Product Description

The manual Flanged type butterfly valve has simple structure, small volume and light weight, and only consists of a few parts. And only need to rotate 90 ° can quickly open and close, simple operation, and the valve has good fluid control characteristics

When the manual gas butterfly valve is in the fully open position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body, so the pressure drop generated through the valve is very small, so it has better flow control characteristics. Butterfly valve has elastic seal and metal seal two types of seal. Elastic seal valve, seal ring can be embedded on the valve body or attached to the butterfly plate peripheral

Butterfly valve is mainly divided into flange butterfly valve and clip butterfly valve and so on, the clip butterfly valve is to use double head bolt to connect the valve between the two pipe flanges, flange butterfly valve is valve with flange, bolt the valve on both ends of the flange connected to the pipe flange

Manual flanged butterfly valve with metal seal valve is generally longer than elastic seal valve life, but it is difficult to achieve complete seal. The metal seal can adapt to the higher working temperature, while the elastic seal has the defects limited by the temperature.If the butterfly valve is required to be used as flow control, the main thing is to correctly select the size and type of the valve. The structure principle of butterfly valve is especially suitable for making large caliber valve.Butterfly valve is not only widely used in petroleum, gas, chemical industry,water treatment and other general industries, but also used in cooling water system of thermal power station
